FEATURES & TECHNICAL EXPLANATION 2-1. FEATURES Anti Crease function With the alternate rotation of the drum, creasing in the laundry is minimized. More economical by Fuzzy Logic System FUZZY Logic System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption. Child-Lock The Child-Lock system has been developed to prevent children from pressing any button (except Power button) to change the programme during operation. Low noise speed control system By sensing the amount of load and balance, this system automatically distributes load evenly to minimize the spinning noise level. Direct Drive System The advanced Brushless DC motor rotates the drum directly without a belt and a pulley. Built-in heater Internal heater automatically heats the water to the best temperature on selected cycles. 4 2-2. DETERMINE WASHING TIME BY FUZZY LOGIC To get the best washing performance optimal time is determined by sensing of water temperature, selected washing temperature and laundry amount. water temperature washing time selected washing temperature FUZZY LOGIC rinse time the best washing performance spin rhythm, time laundry amount SENSING PROCESSING DETERMINATION EFFECT 2-3. WATER LEVEL CONTROL This model adopts a pressure sensor which can sense the water level in the tub. When the water level reaches to the preset level the water supply is stopped, then the washing program proceeds. Spinning does not proceed until the water in the tub reduces a certain level. 2-4. THE DOOR CAN NOT BE OPENED While program is operating. While Door Lock light turns on. 5 3.
